Abstract(in Japanese) (See Japanese page)
Abstract(in English) FDTD method is currently used for the numerical analysis of many electromagnetic problems. About 30 years ago, I was engaged in research on ground penetrating radar where the propagation characteristics of electromagnetic waves between the earth and air and the reflection characteristics of buried pipes are studied, and it is there I encountered the FDTD method. FDTD method is much easier and more accurate than the Sommerfeld’s integral, the high-frequency approximation, and the moment method. Since then, I have used this method for the analysis of scattering and propagation of electromagnetic waves, antennas, and numerical analysis of optical disks. In these studies, I have faced various problems such as dispersive media, anisotropic media, problems involving fine structures, and problems with large computational domains. In this talk, we will introduce some examples of electromagnetic wave analysis using the FDTD method and report some of the know-how of FDTD calculation obtained in my research.
